5. User Instructions
Before turning on gas, check main supply valve to be sure it is open (Fig. 3). Be sure to check all
connections for leaks with a Gas Leak Testing solution, (soap and water work well). Check to see if gas
valve knob is in the ON position. If not, turn counter-clockwise until knob “clicks” into the ON position.
(This may not apply to all units). Turn on gas by turning ball valve handle into vertical position.
5.1 Connecting Electrical Power
Make sure a circuit breaker or similar cutoff device is provided to permit disconnection of
electrical power to heater for service and cleaning. This heater is designed to be wired directly,
with no plugs and outlets necessary. All electrical work should be performed by a certified electrician.
The wiring diagrams on pages 7-8 show how to wire a line power supply directly to the heater’s
terminal block. If no adjustments are made, the heater will operate every time power is supplied and
the on/off switch is activated. If an external thermostat is to be used (See Component & Wiring
Diagram), the heater will operate only when power is supplied, the on/off switch is activated, and the
thermostat indicates a call for heat.
5.2 Starting Up
Adjust thermostat higher than house
temperature. Allow 20 seconds for
heater to ignite. On initial start up or
when heater has not been in service
for some time, heater may require
more than one attempt to purge air
and ignite heater. (IF HEATER
FAILS TO IGNITE. REFER TO
TROUBLE SHOOTING GUIDE).
Adjust thermostat to desired house
temperature.
5.3 Shutting OFF Heater
Shut off main gas supply valve, close
ball valve, and disconnect electrical
power.
